PAP2 — Brassica juncea

Summary

BJUA03G19070S (BjPUP1, also known as PAP2) encodes a protein with PPA-like, MPP_PAP, calcineurin-like_PHP, and metallo-dependent_PP-like domains, and has phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, and binds ferric iron, manganese, and zinc. In Indian mustard, this gene is associated with pigmentation, anthocyanin biosynthesis, and cellular response to phosphate starvation. The protein localizes to the vacuolar lumen, plant-type cell wall, plasmodesmata, and extracellular space. It is linked to flower and petal color traits, as well as phosphate deficiency tolerance and adaptation. Related genes in other species are associated with phosphate starvation responses, phosphate acquisition and utilization, phosphorus uptake, and anthocyanin content.
